AkineteFunction?Resting spores: Cells that

are resistant to unfavorable conditions.

HeterocystFunction? Nitrogen fixation

http://www.botany.hawaii.edu/faculty/webb/bot311/Cyanobacteria/AkineteHeterocystLMHigh300Lab.jpg


The akinetes of Nostoc are usually located halfway between the heterocysts. This differs from Anabaena, where the akinetes are normally adjacent to the heterocysts. (Wikipedia)
